Optical fiber splice encapsulated by a cladding light stripper

Spliced multi-clad optical fibers with a cladding light stripper (CLS) encapsulating the splice. The splice may facilitate conversion between two optical fibers having different architectures, such as different core and/or cladding dimensions. The CLS may comprise a first length of fiber on a first side of the splice, and a second length of fiber on a second side of the splice, encapsulating the splice within the lengths of the CLS. The splice may abut one or more of the lengths of the CLS, or may be separated from one or more lengths of the CLS by an intermediate length of a first and/or second fiber joined by the splice.
